LANGUAGE AND MEANING OF FLOWERS AND PLANTS
We do not know for sure if the hyssop (Hyssopus officinalis) that we know is the one that is handed down in history. It is certain that a plant called hyssop is mentioned several times in the Holy Scriptures at very important moments. 'Old Testament, when the Lord prescribes it for the first Passover: “Go and get yourself a small head of cattle for each of your families and sacrifice the Passover. You will take a bundle of hyssop, you will dip it in the blood that will be in the basin and sprinkle the architraves and the jambs with the blood of the basin. None of you will go out the door of his house until morning. The Lord will pass to strike Egypt, he will see the blood on the lintel and on the doorposts: then he will pass through the door and will not allow the exterminator to enter your house to strike ».
David himself quotes him saying: «Purify me with hyssop and I will be cleansed: I will wash my clothes whiter than snow».
He still mentions the New Testament as hyssop was the rod in which the sponge was fixed and then dipped in the vinegar given to Jesus Christ on the cross.
Hyssop has therefore always been associated with purification, with sacrifice, making this herb sacred.
